Andrew Haigh (Weekend, 45 Years) directed the adaptation of Willy Vlautin's novel, which stars Plummer as a lonely teen who bonds with the titular aging racehorse. Upon learning from the horse's owner (Steve Buscemi) that the animal is set to be slaughtered, the boy takes extreme measures to save its life and heads on a trip across America.

Chloe Sevigny and Travis Fimmel are also among the cast of the film, which first debuted to strong reviews earlier this year at the Venice Film Festival.
